What chin work would I need for pure fat not bone? (Photos)

I do a large amount of chin reduction. To address your chin (if truly just fat) we would go underneath the chin on the neck and remove some of the fleshy parts over the bone. This should be able to provide you with a good amount of improvement.

If this is truly due to excessive fat, then you can absolutely get lipo of just the chin fat pad. It is also possibly due to an excessively active mentalis muscle (treat with botox) or bone, although you would know best since you know what your face feels like! I would consult with someone who can offer all of these options so that you can get the best tailored treatment plan for what you need. It might also help to have some imaging, even an ultrasound in office, to confirm what is causing the chin excessive projection.

Chin reduction can help with a large protruding chin 'Witch's chin'. This is usually an abundance of soft tissue which causes a bulge. The procedure involves making an incision below the chin, accessing the extra soft tissue and removing it while taking care to preserve the muscles. Along with this some skin is removed below the chin to have a pulling effect on the chin and leading to a smaller or less protruding chin.
